This article mainly introduces the QR code generation software implemented by Python. It is implemented using wxPython, python-qrcode, pyqrcode, pyqrnative, and other open-source libraries. For more information, see the following days, I estimate that I can build a QR Code Applet and display it on the screen using wxPy

Android QR code scanning (zxing usage summary) There are three main points: 1. Draw the interface, including four corners, scrolling up and down, and adding text to the canvas 2. Adjust the position of the QR code scan box. 3. Solve the Problem of image deformation. 1. Draw the onDraw () method in ViewfinderView.

The Android version of the Zxing library is a Java version of the code library, but I do not know why there is no C + + version of the decoding library, it can not be decoded on iOS, if the application is to generate two-dimensional code and

, you need to have Python and Jpype installed on your computer, but many computers do not have these. Since most of the computers here have matlab, and MATLAB is integrated with Java, so, wrote a Matlab function, call zxing to generate two-dimensional code.
